It can take years to find a job that is better, but you should polish your resume and start looking. In some cases you should tell your boss that you find the last raise offensive and you so you are forced to start looking - they may have options. But in others talking about it will put you first on the lay-off list before you find a new job, and this in turn may force you to accept a job you don't like as much just because you need some income. (even in countries with a safety net you probably like a nicer lifestyle than the safety net will allow)

The important part is once this starts happening nothing will change until enough people - not just you - force the issue by leaving for someplace that treats you better.

You have indicated an awareness that are are not always perfect. I have no idea how bad you are, there are some people that the company would be better off if they left, and the company has decided you are such a person. Maybe you need to reform yourself? I cannot answer that other than to point out everyone has room for improvement.
